Malware 101: Understanding basics that matter for businesses 

Malware remains among the top cyber threats & risks for businesses around the globe. In simple words, malware refers to a malicious code, software, or program that can be used for varied activities. Hackers, scammers, and cybercriminals, are often interested in spying on user activities, getting access to networks, and data, and sometimes, even again control of operations, servers and IT environments. Many companies have had to deal unwanted consequences following a malware attack, including security ban. In this post, we are discussing more on malware and things that are worth knowing. 

Knowing common malware threats

There are different kinds of malware threats that are directed towards businesses. A good example of that would be ransomware, where hackers gain access to operations and devices, and in return of decryption key, they ask for a ransom. Viruses, on the other hand, are meant to delete and corrupt files, while worms are a type of network malware. Trojans, one of the more serious types of malware, are often used for creating backdoors and to launch further malware attacks. Other examples of malware include adware and spyware. 

How businesses can prevent malware attacks?

  1. Tell your employees about malware. If you are conducting cybersecurity training, ensure that malware remains a subject of continuous discussion. Make sure that employees know of how malware attacks happen and means used for social engineering. 
  2. Use a spam filter. A considerable number of malicious downloads come through emails and phishing mails. Ask your employees to use a reliable spam filter, and make sure that your devices are placed behind firewalls. 
  3. Invest in antimalware software. Ensure that your business invests in antimalware software, and there are quite a few to choose from. There are also special products meant to protect devices and networks from ransomware and spyware. 
  4. Use network segmentation. Instead of storing all sensitive information, resources, and IT assets on one network, consider using network segmentation to create subnetworks. This works pretty much like a firebreak and prevent malware from affecting the entire system. 
  5. Focus on authentication. Ensure that your business uses some form of additional authentication beyond passwords. This could be in form of security questions or extra pins, but passwords shouldn’t allow someone to access critical resources directly. 

Finally, make time to review your security policies. Also establish a few dos and don’ts for safe browsing, and ensure that your employees are well-versed with the basics of malware protection and when to report an incident.
